My entry for the js13kGames JavaScript coding competition for HTML5 game developers.

A remake of the 1978 launched Simon electronic game with HTML5, JavaScript and CSS3.

You can play the game here


The fun part of the compo is the file size limit set to 13 kilobytes. Competition will start at 13:00 CET, 13th August 2012 and end at 13:00 CET, 13th September 2012.

How do I play this?

This is a Keyboard-Only-Game (KOG), so please use your keyboard

Create a new game with the space bar and hit the a, s, d or f key to play!

You still don't get it? TimPietruskyTV has the answer:

Browser support

Best played with the latest WebKit-browsers (Chrome or Safari) because WebKit has much better performance, css filter and css repeating-radial-gradient support.

Playable with Firefox 15.


The game is open source and you can grab it on GitHub:

Thanks goes to

Pedro Ladaria

His riffwave.js can create synthesized sounds from audio data to use with the HTML5 audio element.

Peter Higgins

His small pubsub.js library is capable of sending messages to listeners.
